Musical rendition is provided through the use of microsensors, in particular of accelerometers and magnetometers or rate gyros, and through an appropriate processing of the signals from the microsensors. In particular, the processing uses a merging of the data output from the microsensors to eliminate false alarms in the form of movements of the user unrelated to the music. The velocity of the musical strikes is also measured. Embodiments make it possible to control the running of mp3 or wav type music files to be played back.

The present invention provides a method of processing musical information. A user can perform a musical piece, using a real musical instrument (e.g. a guitar), which is received as audio input. The audio input is then assessed to determine whether it meets various quality standards—for example, whether the user played at the right pitch, at the right time, or at the right volume. If the audio input meets the standards, audio output is then provided of a professional performance of the musical piece, such that it sounds as if the user is performing the professional audio. The standards can be adjusted to different levels, depending on the user's skill on the musical instrument. At an easy level, low standards may be applied, such that even unskilled or beginner musicians can sound like a professional. For more skilled users, the standards may be more difficult to meet. If the user does not meet the quality standards, alternative audio output may be provided, indicating incorrect performance of the musical piece.
